The SMM766 is an Active DC Output power supply Controller (ADOCTM) that monitors, margins, and cascade sequences. The ADOC feature is unique and maintains extremely accurate settings of system supply voltages to within 0.2% under full load. The SMM766 actively controls up to 6 DC/DC converters and can be linked with up to 7 other Sequence-LinkTM devices to accommodate sequencing of up to 48 channels. Control of the DC-DC converters is accomplished through the use of a Trim or Regulator VADJ/FB pin to adjust the output voltage. For system test, the part also controls margining of the supplies using I2C commands. It can margin supplies with either positive or negative control within a range of 0.3V to VDD, depending on the specified range of the converter. The SMM766 also intelligently sequences or cascades the power supplies on and off in any order using enable outputs with programmable polarity. It can operate off any intermediate bus supply ranging from 6V to 14V or from 5.5V to as low as 2.7V. The part monitors 6 power supply channels as well as VDD, 12V input, two general-purpose analog inputs and an internal temperature sensor using a 10-bit ADC. The 10-bit ADC can measure the value on any one of the monitor channels and output the data via the I2C bus. A host system can communicate with the SMM766 status register, margining and utilize 2K-bits of nonvolatile memory.
